It is commonly known as the "Green-flowered Rock Fig Marigold" or "Klipvygie" in Afrikaans. This plant is native to the western and southern Cape of South Africa and can be found growing on rocky outcrops and cliffs.
Appearance
Phyllobolus viridiflorus is a low-growing, mat-forming plant, which usually grows up to 10 cm tall and about 40 cm wide. The plant has small, fleshy, and narrow leaves that are green to light green in color. The leaves are about 2-4 cm in length and 1-3 mm wide. During the growing season, the plant produces showy, bright green flowers that are about 3 cm in diameter.
The flowers are held on short stems and have five petals that are distinct at the base and united at the apex. They also have a yellow center that is surrounded by a ring of green stamens. These flowers usually bloom from late winter to early spring, and their bright green color stands out among the rocky surroundings. The plant's fruit is a capsule that splits at maturity to release seeds.
Uses
Phyllobolus viridiflorus is commonly used as an ornamental plant in a rock garden or as ground cover due to its low-growing habits. It is also drought-tolerant, making it an ideal plant for dry and arid areas. Additionally, the plant is highly sought after by succulent collectors for its unique and stunning green flowers.
Furthermore, several South African tribes use the plant for medicinal purposes. They apply the mashed leaves and stems to treat chest pains and coughs, while the juice from the plant is used to treat earaches. However, it is essential to note that the plant's medicinal uses have not been scientifically proven and should only be used under the guidance of a reputable herbal practitioner.
Light Requirements
Phyllobolus viridiflorus thrives in bright light conditions with exposure to direct sunlight in the morning and evening. However, it is best to avoid intense midday sunlight as it may cause leaf scorching.
Temperature Requirements
Phyllobolus viridiflorus prefers warm temperatures, with an ideal range of 20°C to 30°C during the day and 10°C to 15°C during the night. It is important to avoid temperatures below 5°C as it may cause damage or death to the plant.
Soil Requirements
Phyllobolus viridiflorus prefers well-draining soil with a pH range between 6.0 to 7.5. The soil should be rich in nutrients and organic matter. A combination of coarse sand, perlite, and peat moss can be used to create the perfect soil mix. It is also important to ensure that the soil is not waterlogged to prevent root rot.
Cultivation methods
Phyllobolus viridiflorus is a succulent plant native to South Africa, and it thrives in warm and sunny environments. This plant can be grown indoors or outdoors, and it does well in containers or garden beds. When growing indoors, ensure the room is bright with adequate light. For outdoor gardens, place the plant in an open area that gets at least six hours of sunlight daily. The soil should be well-draining, with a pH between 6.0 and 7.5. Mix sand, perlite, and regular potting soil in equal portions to create a well-draining soil mix.
Watering needs
Phyllobolus viridiflorus requires moderate watering. During the growing season, water the plant thoroughly after the soil dries out. Ensure that the pot or garden bed has adequate drainage to prevent waterlogging. In the winter, reduce the watering frequency.
Fertilization
During the growing season, fertilize with a succulent or cactus fertilizer once a month at half-strength. Apply the fertilizer to the soil around the plant, not directly onto the plant. This will provide the necessary nutrients to keep the plant healthy and vibrant.
Pruning
Phyllobolus viridiflorus requires minimal pruning. Remove any dead or yellow leaves as soon as you spot them to prevent the spread of diseases. During the dormant season, you can trim back any overgrown or unsightly branches to shape the plant.
Propagation of Phyllobolus viridiflorus
Phyllobolus viridiflorus, also known as Aiton, Gerbaulet is a rare and highly sought-after plant by plant collectors. It is native to the southwestern regions of the Western Cape of South Africa where it grows in well-drained soils in full sun. It is a geophyte, which means it has an underground storage organ.
Propagation methods
The plant can be propagated by both seeds and vegetative means such as division and offsets.
Propagation by seed
The seeds of Phyllobolus viridiflorus are small and require careful handling while sowing. They should be sown in a well-draining soil mix in small pots or trays. The best time to sow the seeds is in the fall or early winter, and they should be kept in a warm location with consistent moisture until germination occurs. Once the seedlings are large enough to handle, they can be transplanted into individual pots.
Propagation by division
Division is a suitable propagation method for mature plants that have formed clumps. The best time to divide the clumps is during the plant's dormant period, which is usually in late summer or early fall. The plant should be gently lifted from the soil and the storage organ or corm should be carefully separated into smaller sections. Each section should have at least one healthy shoot and root, and they should be planted in a well-draining soil mix in individual pots.
Propagation by offsets
Offsets are small plantlets that grow at the base of the parent plant. They can be gently separated from the parent plant and planted in a well-draining soil mix in individual pots. It is essential to ensure that each offset has healthy roots and shoots.
Overall, Phyllobolus viridiflorus is a strikingly beautiful plant that can be propagated by seeds, division, or offsets. With proper care, it can be grown indoors or outdoors in temperate climates.
